Pros: 1. Situated on a clean, well maintained ball golf course. Garbage cans, clearly marked holes, grass tees.
2. Staff is great, Good pro shop, plenty of locals to bestow sage like advice.
3. Not a Techniquely challenging course. The course's main challenge is drastic elevation changes (Hole #1 and #5 particularly). Some trees and bushes offer challenges, but not as challenging as the more crowded Morley. Holes #4 and #9 make sure your drives don't tail off the hillsides on the left side of the fairway. can add a couple strokes.
5. Should be able to birdie a few holes.

Cons: 1. Like most courses in SD it is a pay to play $5 wkdy, $6 wknd, $8 for 18 holes..
2. Lot's of ball golf traffic potential on the weekends. 9 hole pitch and putt that draws first timers. I recommend playing during the week when possible, less potential for a ball in the forehead.
3. Obviously they want you to stay off greens and Sandtraps, but most baskets are clear of them.

Other Thoughts: Probably the 3rd best course out of 4 in San Diego county. Play Morley, then Emerald Isle first. Great place to go if you are sick of the Morley crowds, but you don't want to drive up to North County.

Pros: Wide open shots.
Good pin placement
newly installed tee boxes
very little wait if any
Great elevation shots

Cons: Not many precision drives needed
Pretty wet in the morning
Windy in the afternoon
Some of the tee boxes are facing the wrong way

Other Thoughts: I enjoyed this course. I had played ball golf on it many times before, and enjoyed the switch over. It is fun to see your drives sail for a while with the canyon shots. Hole 8 presents a good ace opportunity.
Sun Valley crew is trying to accomodate the disc golfers. The tee boxes are a nice addition, but there are two, (hole 4 and 9) that are set up that the length of the box is in the wrong direction giving the disc golfer only a two foot run up.

Pros:
-Lots of fun elevation shots
-Baskets are in good shape
-Friendly staff
-Discs and food available at pro shop
-Lots of events to participate in
-Windy
-Greens and sandtraps are OB making it more challenging

Cons:
-Grass tees are not fun
-Windy
-Long waits for ball golfers to finish holes at times
-Pay to play (not too bad, keeps grounds up)

Other Thoughts:
Another Disc Golf on a Ball Golf course! Sun Valley is a great course to practice in the wind, and bigger elevation shots. It also helps to thin out the crowds a bit from Morley Field, which is ALWAYS outlandishly crowded.

The tee shots at SV are very fun, throwing up down and across small valleys. And the staff are very pleasant. Moderate amount of well placed vegetation to protect the baskets and add to the challenge, as well as the OB make SV challenging.

The only thing, other than the tees, that annoyed me when I would pay at SV is the ball golfers. It is a pitch-n-putt ball golf course, so you get the guys that bring their friends out that have never played before, and sometimes they have no desire to allow the more serious and competent disc golfers to play through. Generally, everyone is in a good mood though. If you're in San Diego, I would definitely suggest playing Sun Valley over Morley Field, it's just more fun.
